I was really surprised how well a modest VM (Virtual box etc) with Ubuntu + X11 + i3 runs. I use that fullscreen in a virtual desktop to switch between host OS and Linux/i3 and am increasingly surprised by how much time I am finding myself in the "simple" VM which flies and the host OS. I've found it a great way to make a simple first step to switching over on the desktop.
